편백나무 추출물을 함유한 다공성 필름 분석|RISS 상세보기

다국어 초록 (Multilingual Abstract)

This present study was performed to analyze the efficiency and volatility of a porous film containing Chamaecyparis obtusa extract as a method to effectively package food compounds. Phytoncide was contacted the state of gas and showed effective antimicrobial properties. Limonene can be distilled without decomposition as a relatively stable terpene and was one of the extract components. Chamaecyparis obtusa essential oil. The optimal solvent composition was a ratio 5:20:0.3 of T-500:ethanol:hardener to effectively manufacture film containing phytoncide essential oil and the minimum antibacterial concentration was 2%. The films were made under different conditions(A-50LF1, A-25SF2, B-50SF1, C-50LF1, C-25SF2 and D-50SF1) containing phytoncide and the amounts of limonene inside the 1-L reaction chamber depending on storage were measured by gas chromatography-mass selective detention. The results showed that the 25SF2(width, 25 ㎜; length, 20 ㎝) revealed more amount of limonene compared with 50LF1(width 50 ㎜, length 20 ㎝). We confirmed that the gas emission amount showed a better layer on the film side than on the internal film. An effect of film thickness on phytoncide emissions was observed in that the amounts was less than the expectation for a thicker film at the beginning time, but the emitting amounts increased with increasing storage periods. In the storage testing of various films at 35℃ and 70% humidity for 14 days, 25SF2 showed longer preservation compared with that of 50LF in the case of bread. C. obtusa essential oil is a useful fresh ingredients, hence, analysis of limonene emission kinetics from various film was helpful to develop films with an optimal antimicrobial effect, and will allow application of such films in food packaging systems.
